Apparently, the accompanying drawings in the following description show some embodiments of the present invention, and a person of ordinary skill in the art may still derive other drawings from these accompanying drawings without creative efforts.
To make the objective, technical solutions, and advantages of the present disclosure clearer, the following further describes the embodiments of the present invention in detail with reference to the accompanying drawings.
Referring to
101: Buffer, in real time, streaming media data during live broadcast of streaming media.
In this embodiment, the streaming media data includes but is not limited to: a video file or an audio file. The real-time buffering may be buffered in a local device, or may be buffered in a remote server, which is not specifically limited in this embodiment.
Buffering duration may be set according to the size of system space, or may be set according to a requirement of a user. Preferably, the real-time buffering is buffered in a server, and buffering duration is set as entire duration of the live broadcast of the streaming media data. For example, the streaming media data is a live broadcast television program, whose entire duration is 2 hours, and then the buffering duration is set to be 2 hours.
102: Interrupt the live broadcast when a broadcast insertion command is received, to perform broadcast insertion until the broadcast insertion ends, and determine, according to the broadcast insertion command, a start moment for playing the buffering.
The broadcast insertion command is used to instruct the local device to insert broadcast insertion information during the live broadcast, where the broadcast insertion information may be content, which is played in the live broadcast, of the streaming media, or may be other information except the streaming media, which is not specifically limited in this embodiment.
103: Play the buffered streaming media data at a specified speed from the start moment, until a playback process is synchronized with a real-time signal of the live broadcast, stop playback of the buffered streaming media data, and resume the live broadcast.
The specified speed is higher than a live broadcast speed of the streaming media. In this manner, the buffered streaming media data is played at a speed higher than the live broadcast speed, so that a progress of playing the buffering can catch up with a progress of the live broadcast, thereby ensuring that content of the live broadcast is not lost.
In this embodiment, optionally, the interrupting the live broadcast when a broadcast insertion command is received, to perform broadcast insertion until the broadcast insertion ends, and determining, according to the broadcast insertion command, a start moment for playing the buffering may include:
interrupting the live broadcast when a broadcast insertion command for playing broadcast insertion information except the streaming media data is received, and inserting the broadcast insertion information until the broadcast insertion ends; and
determining, according to the broadcast insertion command, that a moment at which the live broadcast is interrupted is the start moment for playing the buffering.
In this embodiment, optionally, the interrupting the live broadcast when a broadcast insertion command is received, to perform broadcast insertion until the broadcast insertion ends, and determining, according to the broadcast insertion command, a start moment for playing the buffering may include:
interrupting the live broadcast when a broadcast insertion command for replaying the streaming media data from a specified moment is received, and playing the buffered streaming media data from the specified moment until the replaying ends; and
determining that a moment at which the replaying ends is the start moment for playing the buffering.
In this embodiment, further, the playing the buffered streaming media data from the specified moment until the replaying ends may include:
playing, at a speed that is the same as or is lower than a speed of the live broadcast, the buffered streaming media data from the specified moment until the replaying ends.
In this embodiment, optionally, the foregoing method may further include:
calculating, according to the start moment for playing the buffering and a current moment, a delay time for playing the buffering; and
determining a corresponding variable speed multiplier according to the delay time, and obtaining the specified speed through calculation according to the variable speed multiplier and the live broadcast speed.
In the foregoing method provided by this embodiment, streaming media data is buffered in real time during live broadcast of streaming media; the live broadcast is interrupted when a broadcast insertion command is received, to perform broadcast insertion until the broadcast insertion ends, and a start moment for playing the buffering is determined according to the broadcast insertion command; and the buffered streaming media data is played at a specified speed from the start moment, until a playback process is synchronized with a real-time signal of the live broadcast, playback of the buffered streaming media data is stopped, and the live broadcast is resumed, where the specified speed is higher than a live broadcast speed of the streaming media; so that after the broadcast insertion, the buffered streaming media data is rapidly played until synchronized with the live broadcast, which not only ensures that no live broadcast information is lost, but also can resume the live broadcast as rapidly as possible, thereby reducing impact on the live broadcast, and improving user experience.
Referring to
201: Buffer, in real time, streaming media data during live broadcast of streaming media.
202: Interrupt the live broadcast when a broadcast insertion command for playing broadcast insertion information except the streaming media data is received, and insert the broadcast insertion information until the broadcast insertion ends.
The broadcast insertion command includes broadcast insertion information, and the broadcast insertion information is not the streaming media data of the live broadcast but other information except the streaming media data. The broadcast insertion information may be read from the broadcast insertion command, and after the live broadcast is interrupted, the broadcast insertion information is inserted for a user.
203: Determine, according to the broadcast insertion command, that a moment at which the live broadcast is interrupted is a start moment for playing the buffering.
In this embodiment, in order not to loss live broadcast information, it is determined that the moment at which the live broadcast is interrupted is the start moment for playing the buffering, so that it is ensured that after the broadcast insertion and when the buffered streaming media data is played, content before the broadcast insertion can be resumed for playback, thereby ensuring integrity of the live broadcast information.
204: Calculate, according to the start moment for playing the buffering and a current moment, a delay time for playing the buffering.
Specifically, the delay time may be obtained by subtracting the start moment for playing the buffering from the current moment, where the delay time indicates a delay time for the live broadcast after the broadcast insertion is completed, and the delay time may be used to determine a speed for playing the buffered streaming media data. For example, when the delay time is long, the speed for playing the buffered streaming media data may be increased, and when the delay time is short, the speed for playing the buffered streaming media data may be reduced, so as to ensure that the speed for playing the buffered streaming media data catches up with a playback speed of the live broadcast.
205: Determine a corresponding variable speed multiplier according to the delay time, and obtain a specified speed through calculation according to the variable speed multiplier and a live broadcast speed.
The variable speed multiplier is a number greater than 1; therefore, the specified speed is higher than a live broadcast speed of the streaming media.
There may be multiple manners for determining the variable speed multiplier according to the delay time. For example, a factor is set, and a delay time is multiplied by the factor to obtain a variable speed multiplier; or a mapping table is set, each delay time in the table corresponds to a fixed variable speed multiplier, and a corresponding variable speed multiplier can be obtained by looking up the table according to a delay time; certainly, an algorithm may also be preset, and a variable speed multiplier is calculated according to the algorithm; and the like, which is not specifically limited in this embodiment. After the variable speed multiplier is obtained, the variable speed multiplier may be multiplied by the live broadcast speed to obtain the specified speed, where the specified speed is used to play the buffered streaming media data.
For example, the delay time is 5 seconds, and the variable speed multiplier is determined to be 1.5 times; therefore, the buffered streaming media data is played at a speed 1.5 times of the original speed, and 10 seconds later, the playback of the buffered streaming media data can catch up with a real-time signal of the live broadcast. For another example, the delay time is 10 seconds, and the variable speed multiplier is determined to be 2.0 times; therefore, the buffered streaming media data is played at a speed 2.0 times of the original speed, and 10 seconds later, the playback of the buffered streaming media data can also catch up with the real-time signal of the live broadcast.
206: Play the buffered streaming media data at the specified speed from the start moment, until a playback process is synchronized with a real-time signal of the live broadcast, stop playback of the buffered streaming media data, and resume the live broadcast.
The method provided in this embodiment is applicable to an application scenario of automotive navigation. For example, a radio is being played in an automobile, and a real-time signal of the radio is buffered at the same time. At a moment, a navigation system needs to play prompt information, and therefore, sends a broadcast insertion command to a live broadcast system. After receiving the broadcast insertion command, the live broadcast system pauses playback of a current live broadcast signal of the radio, and inserts playback of navigation information. After the playback of the navigation information is completed, buffered data is read, and the buffered data is played at a specified speed from a moment at which the live broadcast is interrupted, until a playback process is synchronized with the real-time signal of the radio in the live broadcast; and the playback of the buffered data is stopped, and the live broadcast of the radio is resumed.
In the foregoing method provided by this embodiment, streaming media data is buffered in real time during live broadcast of streaming media; the live broadcast is interrupted when a broadcast insertion command for playing broadcast insertion information except the streaming media data is received, and the broadcast insertion information is inserted until the broadcast insertion ends, and it is determined, according to the broadcast insertion command, that a moment at which the live broadcast is interrupted is the start moment for playing the buffering; a delay time for playing the buffering is calculated according to the start moment for playing the buffering and a current moment, and a corresponding variable speed multiplier is determined according to the delay time, and the specified speed is obtained through calculation according to the variable speed multiplier and the live broadcast speed; and the buffered streaming media data is played at a specified speed from the start moment, until a playback process is synchronized with a real-time signal of the live broadcast, playback of the buffered streaming media data is stopped, and the live broadcast is resumed, where the specified speed is higher than a live broadcast speed of the streaming media; so that after the broadcast insertion, the buffered streaming media data is rapidly played until synchronized with the live broadcast, which not only ensures that no live broadcast information is lost, but also can resume the live broadcast as rapidly as possible, thereby reducing impact on the live broadcast, and improving user experience.
Referring to
301: Buffer, in real time, streaming media data during live broadcast of streaming media.
302: Interrupt the live broadcast when a broadcast insertion command for replaying the streaming media data from a specified moment is received.
The broadcast insertion command includes information related to the replaying, at least includes a start moment for the replaying, and may further include: duration of the replaying, a speed of the replaying, and the like, which is not specifically limited in this embodiment.
303: Play, at a speed that is the same as or is lower than a speed of the live broadcast, the buffered streaming media data from the specified moment until the replaying ends.
Generally, replayed content is important content or content of highlights, and may be replayed at a speed that is the same as the speed of the live broadcast, or may be replayed at a speed that is lower than the speed of the live broadcast, that is, low-speed playback, so that a user can view replayed content more carefully.
In this embodiment, ending of the replay may be directly specified by the broadcast insertion command; for example, duration of the replaying is specified, so that a time at which the replaying ends is determined. Alternatively, ending of the replaying may also be manually triggered by a user; for example, during replaying, a user clicks an end button to end current replaying, which is not specifically limited in this embodiment.
304: Determine that a moment at which the replaying ends is a start moment for playing the buffering.
In this embodiment, because replayed content is a part of content of the streaming media data in the live broadcast and is content before a current moment, after the replaying is completed, it can be ensured that a live broadcast signal is not lost, provided that the buffered streaming media data is resumed for playback from a moment at which the replaying ends, without a need to return to a moment at which the live broadcast is interrupted.
305: Calculate, according to the start moment for playing the buffering and a current moment, a delay time for playing the buffering.
The delay time may be obtained by subtracting the start moment for playing the buffering from the current moment.
306: Determine a corresponding variable speed multiplier according to the delay time, and obtain a specified speed through calculation according to the variable speed multiplier and a live broadcast speed.
In this embodiment, the variable speed multiplier is a number greater than 1; therefore, the specified speed is higher than a live broadcast speed of the streaming media.
307: Play the buffered streaming media data at the specified speed from the start moment, until a playback process is synchronized with a real-time signal of the live broadcast, stop playback of the buffered streaming media data, and resume the live broadcast.
The method provided in this embodiment is applicable to an application scenario of television replaying. For example, a ball game is live on television currently, and a real-time signal of the ball game is buffered at the same time. At a moment, a user clicks a replay button to trigger a broadcast insertion command; therefore, playback of a current live broadcast signal is paused, and replaying of buffered streaming media data is started. After the replaying is completed, the buffered streaming media data is resumed for playback at a specified speed from the ending moment of the replaying, until a playback process is synchronized with the real-time signal of the live broadcast, playback of the buffered streaming media data is stopped, and resume the live broadcast of the ball game.
In the foregoing method provided by this embodiment, streaming media data is buffered in real time during live broadcast of streaming media; the live broadcast is interrupted when a broadcast insertion command for replaying the streaming media data from a specified moment is received; playback of the buffered streaming media data is started at a speed that is the same as or is lower than a speed of the live broadcast and from the specified moment until the replaying ends; and it is determined that a moment at which the replaying ends is the start moment for playing the buffering; a delay time for playing the buffering is calculated according to the start moment for playing the buffering and a current moment, and a corresponding variable speed multiplier is determined according to the delay time, and the specified speed is obtained through calculation according to the variable speed multiplier and the live broadcast speed; and the buffered streaming media data is played at a specified speed from the start moment, until a playback process is synchronized with a real-time signal of the live broadcast, playback of the buffered streaming media data is stopped, and the live broadcast is resumed, where the specified speed is higher than a live broadcast speed of the streaming media; so that after the broadcast insertion, the buffered streaming media data is rapidly played until synchronized with the live broadcast, which not only ensures that no live broadcast information is lost, but also can resume the live broadcast as rapidly as possible, thereby reducing impact on the live broadcast, and improving user experience.

As one type of motion sensor, a gravity acceleration sensor can detect magnitude of accelerations in various directions (generally on three axes), may detect magnitude and a direction of the gravity when static, and may be applied to an application that recognizes the attitude of the mobile phone (for example, switching between landscape orientation and portrait orientation, a related game, and magnetometer attitude calibration), a function related to vibration recognition (such as a pedometer and a knock), and the like. Other sensors, such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which may be configured in the terminal 600, are not further described herein.
The audio circuit 660, a loudspeaker 660a, and a microphone 660b may provide audio interfaces between the user and the terminal 600. The audio circuit 660 may convert received audio data into an electric signal and transmit the electric signal to the loudspeaker 660a. The loudspeaker 660a converts the electric signal into a sound signal for output. On the other hand, the microphone 660b converts a collected sound signal into an electric signal. The audio circuit 660 receives the electric signal and converts the electric signal into audio data, and outputs the audio data to the processor 680 for processing. Subsequently, the processor 680 sends the audio data to, for example, another terminal by using the RF circuit 610, or outputs the audio data to the memory 620 for further processing. The audio circuit 660 may further include an earplug jack, so as to provide communication between a peripheral earphone and the terminal 600.
To implement wireless communication, the terminal may be configured with a wireless communications unit 670. The wireless communications unit 670 may be a WiFi module. WiFi is a short distance wireless transmission technology. The terminal 600 may help, by using the wireless communications unit 670, the user to receive and send e-mails, browse a webpage, access streaming media, and so on, which provides wireless broadband Internet access for the user. Although
The processor 680 is the control center of the terminal 600, and is connected to all parts of an entire mobile phone by using various interfaces and lines. By running or executing the software program and/or module stored in the memory 620, and invoking data stored in the memory 620, the processor 680 performs various functions and data processing of the terminal 600, thereby performing overall monitoring on the mobile phone. Optionally, the processor 680 may include one or more processing cores. Preferably, the processor 680 may integrate an application processor and a modem. The application processor mainly processes an operating system, a user interface, an application program, and the like. The modem mainly processes wireless communication. It may be understood that the foregoing modem may also not be integrated into the processor 680.
The terminal 600 further includes the power supply 690 (such as a battery) for supplying power to the components. Preferably, the power supply may be logically connected to the processor 680 by using a power management system, thereby implementing functions such as charging, discharging and power consumption management by using the power management system. The power supply 690 may further include one or more of a direct current or alternating current power supply, a re-charging system, a power failure detection circuit, a power supply converter or inverter, a power supply state indicator, and any other components.
Although not shown in the figure, the terminal 600 may further include a camera, a Bluetooth module, and the like, which are not further described herein.
